How Can I...

[318iEnthusiast]

Pull off the intake manifold and throttle body to get to the hoses below?  What gasket will I need to replace? and what's the part number?

thanks in advance!

please? anyone?!

Coolant hoses?
Vacuum lines?

dunno about the p/nos but if you havent had it off before you'd want to change the TB gaskets ebtween the inlet manifold and tb, and the upper inlet manifold to lower inlet manifold gasket. while there i'd be tempted to have the lower inlet manifold off too, change its gasket (between it and head) and clean out the injectors/renew their rubber seals.
to do the job first remove airbox, throttle below, afm etc out the way. then remove the throttle body and heater plates (these are a pain and i ditched them a long time ago). then just unbolt the upper inlet manifold and ICV and you're done. the tb heater plates are the worst bit of the job if you have the design with two heater plates. otherwise its straightforward

its a coolant hose...any advice? or pics? what's the easiest way to get the intake off? which bolts do I undo? the 4 that are one the mounts? or?

i've detailed the easiest way to get the intake off. throttle body off first, removing the coolant plates, then intake off. there are more than 4 bolts and they're obvious.
you can see two or three of them on this pic, to the left of the TPS and above the AFM:


not sure what other advice advice exactly you'd like? I think i've told you justa bout everything? removal of intake etc is straightforward as already mentioned, what would you like pics of? just get stuck in, its not a difficult job! you'll need an 11mm socket for the upper inlet manifold and a 10mm long reach socket + extension to get the tb off.
there's not many coolant hoses down there, which one is it?

[318iEnthusiast]

just advice that you would pass on to someone...its a smaller coolant hose down under the throttle body and intake...you can see it but can't reach it...

thanks for the help

Bringing an old thread back to life.
How did you go about deleting the heater plates?
I have my intake manifold off and figured I could do it while its a parts. I guess they help the car run better in the cold? almost like a choke? Did you just run the 2 hoses together?
